[Hematologic changes in workers exposed to radio wave radiation].

Abstract

Haematological parameters were measured in 43 radar operators employed in air traffic control occupationally exposed to microwave radiation of low intensity over a period of four years. Exposure to heat, soft X-ray radiation and noise were within maximally allowed limits. The haematological changes included a decreased number of erythrocytes, reticulocytes, platelets, segmented granulocytes and monocytes, and an increased number of leucocytes and lymphocytes. The changes were not pathologically significant and most of them were reversible.

Main findings

In 43 radar operators occupationally exposed to low-intensity microwave radiation over four years, several blood cell counts decreased (erythrocytes, reticulocytes, platelets, segmented granulocytes, monocytes) while leucocytes and lymphocytes increased. The reported changes were not pathologically significant and most were reversible.

Outcomes measured

• hematological parameters (erythrocytes, reticulocytes, platelets, segmented granulocytes, monocytes, leucocytes, lymphocytes)

Limitations

• No exposure metrics (e.g., frequency, power density, SAR) reported in abstract
• No control/comparison group described in abstract
• Potential co-exposures noted (heat, soft X-ray radiation, noise) though stated to be within allowed limits
• Clinical significance described as not pathologically significant

Suggested hubs
